Product Description

Fish Collagen Oligopeptides are small-molecule collagen oligopeptides produced from fresh deep-sea fish skin and fish bones via controlled targeted biological enzymatic hydrolysis and membrane separation purification. The whole production process includes raw material pretreatment, impurity removal, enzymatic cleavage, multi-stage membrane filtration, concentration and low-temperature spray drying.

Macromolecular collagen is degraded into short-chain peptide fragments with concentrated molecular weight distribution. The finished powder is fine and loose with good flowability and excellent water solubility. Specially treated for odor reduction, it maintains stable physicochemical indicators across batches under strict microbial control. As marine-sourced collagen peptide ingredients, it adapts to multiple dosage form processing technologies and is widely used in the formulation development of nutritional products.

Functions and Effects

◆ Controllable Molecular Weight Range

Supported by membrane separation and refining technology, the peptide segments feature concentrated molecular weight range which can be adjusted to meet customers' formulation requirements, ensuring stable material performance during processing.

◆ High Transparency of Aqueous Solution

The powder disperses and dissolves rapidly in water. The resulting aqueous solution is clear and transparent without easy turbidity, suitable for transparent beverage formulations with requirements on liquid appearance.

◆ Optimized Flavor Performance

A dedicated deodorization procedure is integrated into production to greatly reduce inherent aquatic odor of raw materials, minimizing interference to the original flavor of finished goods and lowering the difficulty of formula flavor adjustment.

FAQ

Q1：What is the raw material source of this Fish Collagen Oligopeptides, and what is its appearance?

A：This product is sourced from marine fish skin and processed through enzymatic hydrolysis, deodorization, purification and other procedures. The finished product is fine white or off-white uniform powder, and no obvious caking will occur under proper storage conditions.

Q2：Q: How is the dissolution performance of Fish Collagen Oligopeptides in water of different temperatures? Will there be delamination or turbidity?

A：The product features good water dispersibility and can disperse gradually in room-temperature or warm water. The clarity of the final solution relates to dosage and pH value of the solvent. Slight turbidity may appear at high addition levels. Samples are available for you to test in your own formula system in advance.

Q3：Can you send samples? What are the sample package specifications and logistics arrangements?

A：We offer samples for formula trial and internal testing. Samples are normally packed in sealed aluminum foil bags, and sample quantity can be negotiated according to your requirements. The freight cost of samples is usually borne by the buyer. We can arrange international courier service and share the tracking number after shipment.

Q4：What supporting documents can you provide for bulk orders of Fish Collagen Oligopeptides? Are compliance declarations available?

A：Batch-specific COA, specification sheet, packing list and commercial invoice can be supplied for each shipment.

Q5：What are the proper storage methods and shelf life for Fish Collagen Oligopeptides? What precautions should be taken after opening?

A：Unopened products should be stored in a cool, dry and dark warehouse, away from humidity and heat sources. The standard shelf life is 24 months. Once opened, the package needs to be tightly sealed and consumed as soon as possible to avoid long-time exposure to air and moisture which may cause sensory changes.

Q6：What is the odor characteristic of Fish Collagen Oligopeptides? Will there be obvious flavor differences between batches?

A：The product is processed with dedicated deodorization treatment. It has faint fish-related notes with light inherent raw material flavor, without added flavorings. Slight sensory difference may exist between batches due to different fishing seasons of raw materials. Every batch passes sensory inspection before delivery within acceptable range.

Q7：What is the MOQ of this raw material? What is the bulk packing type and lead time?

A：The regular MOQ is negotiable. Stock goods are packed with food-grade inner bag and outer carton, standard package is 25kg per carton. Lead time is short for in-stock orders.

Q8：Can the molecular weight index of Fish Collagen Oligopeptides be adjusted? What molecular weight ranges are commonly available?

A：Molecular weight distribution can be customized on request. Popular specifications fall within low molecular weight ranges. Products with different molecular weights show different dissolution behaviors. It is recommended that you test the matched sample first before confirming the final purchase specification.
